With the Square Impact, the ProCircuit team wanted to make a tire that compares with other leading brands compounds. So after several sessions designing, and receiving inputs from team drivers, they developed the Square Impact. Wear is always critical when going to a small pin tire, but this tire has been designed for maximum performance when new or used as the design allows even wear all the way down to the tire body. Square Impact excels on indoor and outdoor hard slick surfaces with either dry or wet conditions. These tires offer less sidewall flex, improved response and offer an overall saving of weight. The distance between center bars offer much more forward traction than other small pins treads.
